Constructor Detail

CrossOverDescriptor

public CrossOverDescriptor(ServiceLocator local,
                           ActiveDescriptor<T> localService)

Method Detail

isReified

public boolean isReified()

This method returns true if this descriptor has been reified (class loaded). If this method returns false then the other methods in this interface will throw an IllegalStateException. Once this method returns true it may be

Specified by:

isReified in interface ActiveDescriptor<T>

Overrides:

isReified in class AbstractActiveDescriptor<T>

Returns:

true if this descriptor has been reified, false otherwise

checkState

private void checkState()

getImplementationClass

public java.lang.Class<?> getImplementationClass()

Description copied from interface: ActiveDescriptor

The implementation class that should be used to generate new instances of this descriptor.

If the class returned is a Factory, then the factory is used to create instances. In this case the system will get an instance of the factory and use it to create the instances

Returns:

The class that directly implements the contract types, or the class that is the factory for an object that implements the contract types

getImplementationType

public java.lang.reflect.Type getImplementationType()

Description copied from interface: ActiveDescriptor

If known the Type of the implementation. If unknown will return the same as ActiveDescriptor.getImplementationClass()

Returns:

The type of the implementation or the implementation class

setImplementationType

public void setImplementationType(java.lang.reflect.Type t)

Overrides:

setImplementationType in class AbstractActiveDescriptor<T>

getContractTypes

public java.util.Set<java.lang.reflect.Type> getContractTypes()

Description copied from interface: ActiveDescriptor

The set of types that this ActiveDescriptor must produce. These types may be Classes or ParameterizedTypes, and may be no other subclass of Type

Specified by:

getContractTypes in interface ActiveDescriptor<T>

Overrides:

getContractTypes in class AbstractActiveDescriptor<T>

Returns:

the set of types this ActiveDescriptor must implement or extend

getScopeAsAnnotation

public java.lang.annotation.Annotation getScopeAsAnnotation()

Description copied from interface: ActiveDescriptor

Returns the scope as an Annotation implementation that this ActiveDescriptor belongs to

Specified by:

getScopeAsAnnotation in interface ActiveDescriptor<T>

Overrides:

getScopeAsAnnotation in class AbstractActiveDescriptor<T>

Returns:

The scope of this ActiveDescriptor as an Annotation

getScopeAnnotation

public java.lang.Class<? extends java.lang.annotation.Annotation> getScopeAnnotation()

Description copied from interface: ActiveDescriptor

Returns the scope that this ActiveDescriptor belongs to

Specified by:

getScopeAnnotation in interface ActiveDescriptor<T>

Overrides:

getScopeAnnotation in class AbstractActiveDescriptor<T>

Returns:

The scope of this ActiveDescriptor

getQualifierAnnotations

public java.util.Set<java.lang.annotation.Annotation> getQualifierAnnotations()

Description copied from interface: ActiveDescriptor

The full set of qualifiers that this ActiveDescriptor provides

Specified by:

getQualifierAnnotations in interface ActiveDescriptor<T>

Overrides:

getQualifierAnnotations in class AbstractActiveDescriptor<T>

Returns:

The set of annotations that this ActiveDescriptor provides

getInjectees

public java.util.List<Injectee> getInjectees()

Description copied from interface: ActiveDescriptor

Returns the full list of Injectees this class has. These references will be resolved prior to the class being constructed, even if these injectees are field or method injectees.

If this descriptor is describing a factory created type then this list must have zero length

Specified by:

getInjectees in interface ActiveDescriptor<T>

Overrides:

getInjectees in class AbstractActiveDescriptor<T>

Returns:

Will not return null, but may return an empty list. The set of Injectees that must be resolved before this ActiveDescriptor can be constructed

getFactoryServiceId

public java.lang.Long getFactoryServiceId()

Description copied from interface: ActiveDescriptor

If this ActiveDescriptor has DescriptorType of PROVIDE_METHOD then this field will return the ServiceId of its associated Factory service. Otherwise this method should return null

Specified by:

getFactoryServiceId in interface ActiveDescriptor<T>

Overrides:

getFactoryServiceId in class AbstractActiveDescriptor<T>

Returns:

The service ID of the associated factory service

getFactoryLocatorId

public java.lang.Long getFactoryLocatorId()

Description copied from interface: ActiveDescriptor

If this ActiveDescriptor has DescriptorType of PROVIDE_METHOD then this field will return the ServiceId of its associated Factory service. Otherwise this method should return null

Specified by:

getFactoryLocatorId in interface ActiveDescriptor<T>

Overrides:

getFactoryLocatorId in class AbstractActiveDescriptor<T>

Returns:

The locator ID of the associated factory service

create

public T create(ServiceHandle<?> root)

Description copied from interface: ActiveDescriptor

Creates an instance of the ActiveDescriptor. All of the Injectee's must be created prior to instantiation, and associated with the ExtendedProvider so that they can be destroyed properly

Parameters:

root - The root service handle, which can be used to associated all the PerLookup objects with this creation

Returns:

An instance of this ActiveDescriptor

dispose

public void dispose(T instance)

Description copied from interface: ActiveDescriptor

Disposes this instance. All the PerLookup objects that were created for this instance will be destroyed after this object has been destroyed

Specified by:

dispose in interface ActiveDescriptor<T>

Overrides:

dispose in class AbstractActiveDescriptor<T>

Parameters:

instance - The instance to destroy
